Hello world/Newline omission

Pete: /* {{header|Limbo}} */ Apparently it's "Good-bye" here. Sorry!

{{task|Basic language learning}}

Some languages automatically insert a newline after outputting a string, unless measures are taken to prevent its output. The purpose of this task is to output the string "Goodbye, World!" without a trailing newline.

The quoted form guarantees there are no hidden trailing spaces after World!

'''If delayed expansion is enabled, then the ! must be escaped'''

Escape once if quoted form, twice if unquoted.

=={{header|BBC BASIC}}==
REM BBC BASIC accepts the standard trailing semicolon:
PRINT "Goodbye World!";

REM One could also output the characters individually:
GW$ = "Goodbye World!"
FOR i% = 1 TO LEN(GW$)


put$"Goodbye, World!"

In C, we do not get a newline unless we embed one:

int main(int argc, char *argv[]) {
(void) printf("Goodbye, World!"); /* No automatic newline */

However ISO C leaves it up to implementations to define whether or not the last line of a text stream requires a new-line. This means that the C can be targetted to environments where this task is impossible to implement, at least with a direct text stream manipulation like this.

In C++, using iostreams, portable newlines come from std::endl. Non-portable newlines may come from using constructs like \n, \r or \r\n. If we don't use any of these, we won't get a newline.

int main(int argc, char *argv[]) {
std::cout << "Goodbye, World!";

Native output in Icon and Unicon is performed via the ''write'' and ''writes'' procedures. The ''write'' procedure terminates each line with both a return and newline (for consistency across platforms). The ''writes'' procedure omits this. Additionally, the programming library has a series of ''printf'' procedures as well.

'''Notes''': J programs are normally run from a REPL, or session manager, which comes in several flavors. The traditional commandline-based terminal (jconsole), one of several desktop applications (jqt for the current version of J, jgtk and jwd for older but still supported versions), a web-based frontend (jhs), and various mobile apps (J for iOS, Android).

The specific session manager being used changes the context and therefore answer to this task. For example, when using J from a browser (including mobile browsers) newlines are omitted by default. Further, J provides strong tools for coalescing results and manipulating them prior to output, so newline elimination would typically happen before output rather than after.

With that said, prompt handles the most common cases (using binary output for jconsole, so no newline is appended; adjusting the REPL prompt in the desktop apps to to elide the newline which is normally included by default, etc).

For truly automated processes, you'd almost always want this kind of functionality (omitting the newline when printing) in a file- or stream-oriented application. For those cases, the simple text 1!:3 file will append the text to the referenced file verbatim, without inserting any extra newlines.

So, if a J programmer were asked to solve this task, the right approach would be to ask why that is needed, and then craft a solution appropriate to that situation.

public class HelloWorld
public static void main(String[] args)
System.out.print("Goodbye, World!");

Julia provides a println function which appends a newline, and a print function which doesn't:
print("Goodbye, World!")

Lasso provides a stdoutnl method that prints a trailing newline, and a stdout method that does not:
stdout("Goodbye, World!")

===Simple solution===
In ML/I, if there isn't a newline in the input, there won't be one in the output; so a simple solution is this (although it's hard to see that there isn't a newline).
Goodbye, World!
===More sophisticated solution===
To make it clearer, we can define an ML/I ''skip'' to delete itself and an immediately following newline.

It should be noted that upon a REXX program completion, any text left pending without a C/R (or newline) is followed by a

blank line so as to not leave the state of the terminal with malformed "text lines" (which can be followed by other text

(lines) from a calling program(s), or the operating system (shell) which is usually some sort of a "prompt" text string.

=={{header|UNIX Shell}}==
The ''echo'' command is not portable, and echo -n is not guaranteed to prevent a newline from occuring. With the original [[Bourne Shell]], echo -n "Goodbye, World!" prints -n Goodbye, World! with a newline. So use a ''printf'' instead.

{{works with|Bourne Shell}}

printf "Goodbye, World!" # This works. There is no newline.
printf %s "-hyphens and % signs" # Use %s with arbitrary strings.

Unfortunately, older systems where you have to rely on vanilla Bourne shell may not have a ''printf'' command, either. It's possible that there is no command available to complete the task, but only on very old systems. For the rest, one of these two should work:

echo -n 'Goodbye, World!'
echo 'Goodbye, World!\c'

The ''print'' command, from the [[Korn Shell]], would work well, but most shells have no ''print'' command. (With [[pdksh]], ''print'' is slightly faster than ''printf'' because ''print'' runs a built-in command, but ''printf'' forks an external command. With [[ksh93]] and [[zsh]], ''print'' and ''printf'' are both built-in commands.)
